Description

CROSS REFERENCE TO THE RELATED PATENT APPLICATION

This application claims the priority of the Chinese patent application No. 200610078743.6, filed on May 11, 2006.

FIELD OF THE INVENTION

This invention relates to a method of fabricating silk weaving fabric, especially a method of fabricating jacquard fabric of different characteristics that is suitable for weaving color fabric combining manual designed pattern card and computerized color-clustered image.

BACKGROUND OF THE INVENTION

Traditional color jacquard fabrics mainly represent natural colors of silk yarns in the form of float of warp and filling yarns of different colors. Such colors are simple. However, if color contents are rich, the warp and filling yarns of many different colors have to be used. For a classical example, a product of Hangzhou DuJinsheng Silk Weaving Mill adopts 15 shuttles to weave 15 colors in the pattern and represent scores of texture and color variation (normally colors represent the texture). Although traditional color jacquard pattern uses manual pattern processing and presents good 3-dimensional effect and flexibility, yet it lacks rich colors because it relies on the number of each texture to display a color. The invention patents (ZL99125610.7 and ZL00126505.9) of this inventor proposes a method of color clustering and texture combining to utilize only several color yarns and system textures to weave and represent complicated and plentiful pattern colors. The color-representing texture thus combined can reach thousands of varieties (larger number can be obtained theoretically). Such fabrics present an effect of color photo and painting that cannot be viewed in traditional technique, featuring a character of rich color variation and a breakthrough of technique and theory of modern jacquard design established by Europeans and used in more than a century. However, the pedestrian textures given by computers lack the flexibility of manual pattern processing in traditional designing method, such as changeful manual interlacing to embody elegant character of jacquard fabric.

SUMMARY OF THE INVENTION

This invention relates to a technical program and the method to solve the above-mentioned shortcoming by providing a method of fabricating color jacquard fabric with different characteristics. It combines both pattern cards of computerized color clustering and manual design and interlacing into one pattern card to enable the fabric to feature vivid lifelike picture, rich colors and artful design.

The technical program given in this invention to solve the existing problem is: a method of fabricating color jacquard fabric with different characteristics, with the following steps: (i) design and fabrication of pattern card; (ii) loom preparation; (iii) looming and weaving, wherein the present invention is characterized by the following steps of pattern card design and fabrication:

(1) Read target image for jacquard into a computer by scanner or digital camera;

(2) Adjust the image obtained and set relevant parameters;

(3) Select image pixel according to image dimensions with pixel value corresponding to the number of warp yarn and filling yarn;

(4) Conduct image modification and adjustment;

(5) Divide said modified image into two parts—motif image and auxiliary pattern around the motif image, conduct the design of image and pattern of different design characteristics with computer-aided jacquard design software and then fabricate the pattern card;

(6) Combine said two pattern cards completed to form a pattern card on which warp yarns and filling yarns correspondently display an image and pattern of different design characteristics, and save it to a file. In combining the pattern cards of vivid motif image and auxiliary pattern, pay attention to the coordination between warp and filling yarns order and texture at the joint of two pattern cards.

The main steps of designing and fabricating the pattern card of rich color image are:

A. Adjust the light-shade gradation of target image displayed in the computer and on the chromatogram, configure several colors to conduct color clustering as required;

B. Conduct color segmentation according to the configuration in the above-mentioned step A and combine with black & white into plentiful color combination, then input texture of pattern card successively as per light-shade relation.

C. Save the above-mentioned design to a pattern card file.

A step between B and C may be added that the pattern cards of several colors clustered in B should be stringed and combined to weave more colored fabric.

In pattern card fabrication, computerized image color clustering is adopted. Firstly cut down image colors to only several colors and then conduct color combination. As above said, color combination can provide more than a thousand of colors and these combined colors can form a lifelike weaving image to a verisimilitude extent greatly higher than common color jacquard with just scores of colors. Since the method needs only several kinds of color yarn (some tendentious color yarns may be added if needed), the fabric is characterized by easy fabrication, simple operation and freewill color combination.

The main steps of fabricating auxiliary pattern card are:

A. Conduct skeleton edge enhancement of auxiliary pattern according to design requirements and paint different colors onto different texture. The color of figure flat painting shall be identical to the color of edge enhancement. The color filled in edge enhancement may be selected at will so long as different colors are painted for different texture to show the distinction.

C. By texture weaving software, save said auxiliary pattern to a file.

Though such woven fabrics have less color variation, yet they have strong 3-dimensional effect, flexible manual interlacing and excellent originality.

The steps of said loom preparation are as follows:

(1) Use one color yarn as warp or filling yarn from several color or black/white yarns required by the design, with other color yarns as the other yarn left in warp or filling yarn, and conduct the processes of warp beaming and cop winding;

(2) Adjust looming parameters according to varieties and specifications, such as the size, density and silk yarn variety.

Said steps of looming and weaving are: install the finished pattern card in the loom and start the loom to fabricate the color jacquard fabric of different design characteristics.

Said motif image relates to the image to design the pattern card in accordance with computerized color clustering. Both motif image and auxiliary pattern do not depend on their locations or occupied areas but depend on the means of forming, and the locations and occupied areas of both motif image and auxiliary pattern can be interchanged.

The advantages of this invention lie in that the fabrics produced by this invention can represent not only the beauty like manual interlacing but also the vivid and beautiful color interweaving effect of texture produced by computer software, namely, simultaneously representing: strong dimensional style of manual designed pattern, vivid shaping and rich color patterns designed by the method of computerized color clustering; patterns of fabrics are jointed skillfully, displaying colorful, vivid and lifelike picture with high ornamental value.

An embodiment of this invention is further explained in combination with the figures hereunder.

1. Scan a color scenery picture (as shown in FIG. 2 and FIG. 4) with a color scanner connected to a computer, beginning with a preview;

2. Adjust scanning parameters according to the image of preview. In the case of 300 dpi resolution, the warp (longitudinal) pixels should be 3485 and weft (lateral) pixels 2450;

3. Adjust the color, brightness and contrast of the image scanned. Then make scanning and save the image in a disk;

4. Scan the edging pattern (as shown in FIG. 2 and FIG. 3) designed for frame and save the image in a disk;

5. Open professional computer-aided design software and conduct combined image design, mainly including image design, adjustment, treatment, cropping and despeckle, so as to ensure part of scenery picture to be positioned in the framed pattern, then adjust the combined image dimensions to 3000×2100 pixels;

7. Open said image files in CAD software and conduct pattern card fabrication. For example, open red color separated image file in CAD software to configure it to several transitional textures from red to white. Then conduct such processes to yellow, blue and black color separated image files. As a result, every set of warp and filling yarns weaving constitutes a set of solid color pattern card with the variation of light and shade;

8. Combine said four pattern cards in the order of scarlet, yellow mid, cyan blue and black with the identical order to correspondent wefting yarns. If needed, the four color pattern cards can be stringed and combined in this step;

9. Open the file of edging pattern designed for frame and conduct pattern card fabrication;

10. Conduct skeleton edge enhancement of pattern design and paint different colors onto different texture of frame pattern. For example, if there are two textures of frame pattern design and a ground weave, white may be applied to ground weave, tangerine to pattern design A and golf green to pattern design B. Tangerine and golf green may be configured separately as a set of warp figure comprising mainly warp float and weft figure comprising mainly weft float. If figure flat painting is not simple circulating texture, manual yarn interlacing treatment may be conducted in design as needed with identical coloring of figure flat painting and skeleton edge enhancement;

11. Make the pattern card in accordance with the pattern design and texture configuration;

12. Combine the pattern cards made from step 5 to 7 and the pattern card made from step 8 to 11 to form a complete pattern card file, namely the combining of two matching pattern cards with precise coordination of order and structure at the joint of two pattern cards;
